This is the Maya scene:

As you can see, the walls, paintings, and other objects are transparent. How can this be fixed?

Maya is not doing backface culling. Unity is. You probably just need to flip your normals, but searching for “Unity Cull Off” should help teach you about this if you care to learn.
